You should point DSN to the SQL Server either by it's name on the network or by IP address.

>and if i'm using virtual pc the SQL server that i want to select still can put it as LOCAL?
or should be the name of that server?

You can only refer to SQL Server as (local) if it is installed as default instance on the PC where you're creating DSN.
